LE ROY WV. FAIRCHILD, OF NEXV YORK, N. Y.

FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 325,663, dated September 8, 1885.

Application filed May 20, 1885. (No modem To all whom it may concern:

Be it known that I, Ln Ro W. FAIBCHILD, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Fountain-Pens, of which the following is a specification.

This invention relates to that class or style of fountaiupeus which make use of an ordinary metallic pen-point for writing, and have a tubular handle to serve as an ink reservoir or fountain and the invention consists in a novel construction and arrangement of the parts, as hereinafter more fully set forth.

Figure 1 is a longitudinal section showing one style of metallic pen, with an arrangement for feeding the ink to the under side of the same. Fig. 2 is a similar view showing a slight modification to adapt it to a different style of pen-point, with the ink fed to the back of the same; and Fig. 3 is a side view of the ink-feeding tube detached and slightly modified in form.

Many efforts have been made to produce a fountain-pen in which the ordinary style of gold or steel penpoints could be used without becoming clogged, or from which the ink would not drop at times, and thus blot or mar the paper.

The object of my present invention is to produce such a pen, and at the same time to so construct it that it shall be very simple and easily taken apart for cleaning or washing the parts when desired, and one in which any ordinary gold or steel pen may be used.

To construct a pen on my plan, I provide a tubular handle, A, the upper end of which is closed, as shown in Figs. 1 and 2, its lower end being left open and provided with an in ternal screw-thread. Ithen providea tubular mouthpiece, B, having a somewhat smaller bore, the upper end of which is fitted to screw into the open end of the part A, as shown in Figs. 1 and 2, the bore being preferably formed without any shoulders or offsets, and of a diameter to permit the pen-p0int c to be inserted and hold therein, as shown. I then provide a small tube, I, of proper diameter to lit within the bore of the mouth-piece B, it being made slightly conical, as shown more clearly in Fig. 3, so it can be crowded into place and be securely held by friction alone. The bore of this inner tube, I, which is designed to feed the ink to the pen-point e, is made conical, as shown, so that its lower opening, 0, is quite small. From this point it is out a 'ay on one side to its outer extremity, thus leaving a slender tongue-piece, Z, which projects a little beyond the end of the mouthpiece B, and rests against the pen-point e, as represented in Figs. 1 and 2. This feedingtube I is made of such a length that its upper end shall extend up beyond the mouth-piece B into the chamber of the reservoir A to a greater or less extent, but is either provided with holes just above the inner end of the piece B, as shown in Fig. 2, or is cutaway on one side to near that point, as shown in Figs. 1 and 8. By this arrangement of the tube I in' relation to the mouth piece or section B it will be seen that a small chamber or recess, a, is formed at the lowest point in the reservoir A, between the walls thereof and the exterior of the tube I, immediately below the point at which the ink enters the feeding-tube I, and that thus the sediment,whioh all inks deposit more or loss, can settle in this chamber n, and be prevented from flowing down to the pen point.

In Fig. 2 I have shown a flat form of penpoint, e, and when such a one is used the prongl of the feeder I may be arranged to conduct the ink to the upper side of the pen e, as shown; but when the ordinary concave form of pen is used, as shown in Fig. 1, the prong l is prcferabl y arranged to bear upon and conduct the ink to the under or concave side of the pen 0.

By slitting the lower portion of the feeder I, as shown in Fig. 8, and having a shorter prong, '5, extend part way do wn, it may be made to aid in holding the pen-point c, the upper end of which, in that case, would rest in said slit between the prongs Z and '1 the prong I still serving to conduct the ink to the point e, and being arranged to feed the ink upon the under or upper side of the pen-point c, as may be found most desirable.

This detachable and reversible feeder I, which is also adjustable longitudinally, I consider a very important feature, as it can be adjusted to suit nearly all kinds and various sizes of metallic pens or points, and can be arranged to conduct the ink to either side of the pen-point, as may be desired, some forms of points operating best with the ink on one side, and other forms best with the ink on the opposite side or face.

A cap, 0, is provided to slip over the end to protect the pen, and by shutting off the airsupply prevent the ink from flowing out when not in use. By making the hole 0 of the proper size sufficient air will enter to permit the ink to flow gradually, as is well understood by those skilled in the art, and there being no air-inlet at any other point, the ink will not drop out, as is frequently the case with those fountains which have an air-inlet at the upper end, or a very large one at the lower end.

The device as a whole is exceedingly simple, and cheap of construction, can be easily taken apart for cleansing, and can be adjusted as circumstances may require.

Having thus described my invention, what I claim is- 1. The combination of .the tubular handle or reservoir A, having its upper end permanently closed, the tubular pen-holding section B, and the reversible and adjustable ink-feeder I, all constructed and arranged to operate substantially as shown and described.

2. As an improvement in fountain-pens, the ink-feeder I, consisting of atube having a reduced orifice, 0, at its lower end, and having a prong, Z, extending from one side of said orifice downward, as shown, to bear against and conduct the ink to the back or to the under side of the pen, as set forth.
